SAFETY RAZOR FRAME Filed Feb. 23, 1944 Patented June 11, 1946 SAFETY RAZOR FRAME George Elvis Mignon, Sydney, New South Wales, Australia Application February 23, 1944, Serial No. 523,589 In Australia August 13, 1943 3 Claims. 1

This invention relates to safety razor frames of the type adapted to hold a double edge blade in operative position. The invention has been devised to provide a safety razor frame of this type having the blade keep and blade base made wholly or mainly of sheet metal which is formed into a novel shape by die stamping and the handle can also be made by automatic machinery. The several parts are so made that assembly operations in the manufacture of the safety razor frame are reduced to a minimum and a cheap and efiicient article is produced, A further feature of the invention is in the formation of the blade keep whereby one edge of the blade held in the razor frame is more exposed than the other.

The invention is illustrated in the annexed drawing wherein Fig. 1 is a perspective view of the several parts assembled; Fig. 2 is a perspective view of the several parts separated; Fig. 3 is a fragmentary elevation partly in section showing how the blade keep and blade base are secured by the handle; Fig. 4 is a sectional elevation through the blade keep and the blade base showing a razor guide pin; Fig. 5 is a fragmentary elevation in section of a modification.

Referring to Figs. 1 to 4 the blade keep I is a rectangular stamping made arcuate; it has razor blade guide pins ll formed by cutting U shaped slots therein and pressing out the metal tongues formed between the limbs of the U; it also has a centrally positioned hole l2 with a screw thread therein to take the screwed end l3 of a handle I 4. One longitudinal edge l of this blade'keep is chamfered and the other longitudinal edge I6 is set at an oblique angle. By this construction of the edges l5-l6 one edge of a razor blade held by the blade keep is more exposed than the other. The edge most exposed may be used to shave a tough beard and the other edge used to shave a soft beard; or the different formation of the edges may be used as an indicator of the edge of the razor blade being used or previously used.

The blade base I1 is also a rectangular stamping made arcuate. The curvature of the crown of the blade base extending over the area contacted by that part of a razor blade pressed thereon by the blade keep i0 is slightly less than the curvature of the blade keep II), From the longitudinal edge position of the blade keep Ill on the blade base (indicated at l8) to the edges 19 thereof the curvature is slightly greater than that of the blade keep. Holes 20 in the blade base take the guide pins ll of the blade keep and 20 the respective parts thereof.

there is a central clearance hole 2| through which the screwed end I3 of the handle passes. Near the edges IS the blade base is slotted as shown at 22. The blade keep It extends approximately 5 half way across these slots 22; they constitute passages through which shaving accumulations forming on the razor may pass.

Handle I4 is of metal or it has a metal screwed end l3 to home in the screw hole l2 of the blade keep 10. A shoulder 23 abuts the blade base I! and so holds the several parts together.

It will be appreciated that the width of the blade keep II] is slightly les than a razor blade. When a razor blade is clamped between the blade base and the blade keep the edges |5-l6 of the 25 ception that a screw l3a is permanently affixed in the hole Hat by riveting or otherwise. The handle Ma has a hole in the end thereof with a screw thread to take the screw [3a.

I claim:

1. A safety razor frame consisting of a blade keep being a rectangular stamping made arcuate and having razor blade guide pins formed by cutting U shaped slot in the blade keep and pressing out the metal tongues formed between the limbs of the U perpendicular to the surface of said keep; a blade base underlying said blade keep and of greater transverse width than said blade keep said blade base being a rectangular stamping made arcuate and having the curvature of the crown less than that of the blade keep and the curvature of the part projecting beyond the blade keep greater than that of the blade keep, said blade base having holes to take the razor blade guide pins and a plurality of longitudinal slots aligned in end to end relation adjacent the longitudinal edges thereof and having solid portions of said base between adjacent ends of said slots, said aligned slots being transverse- 1y overlapped by the longitudinal edges of said 5 blade and blade keep which bear on said solid portions, said base having a hole to take a clamping screw; a handle and means whereby the blade keep the blade base and the handle are assembled in operative position.

2. A safety razor frame consisting of a blade I having the curvature of the crown less than that of the blade keep and the curvature of the part projecting beyond the blade keep greater than that of the blade keep, said blade base having holes to take the razor blade guide pins and a plurality of longitudinal slots aligned in end to end relation adjacent the longitudinal edges thereof and having solid portions of said base between adjacent ends of said slots, said aligned slots being transversely overlapped by the longitudinal edges of said blade and blade keep which bear on said solid portions, said base having a hole to take a clamping screw; a handle having a screwed end adapted to pass through said blade base and to take in the screw thread in said blade keep, said handle also having a shoulder to abut said .blade base.

3. A safety razor frame consisting of a blade keep being a rectangular stamping made arcuate and having razor blade guide pins formed by cutting U shaped slots in the blade keep and pressing out the metal tongues formed between the limbs of the U perpendicular to the surface of said keep, and having ascrew projecting therefrom between said slots; a blade baseunderlying said blade keep and of greater transverse width than said blade keep said blade base being a rectangular stamping made arcuate having the curvature of the crown less than that of the blade keep and the curvature of the part projecting beyond the blade keep greater than that of the blade keep, having holes to take the razor blade guide pinsand the said screw and a plurality of longitudinal slots adjacent the longitudinal edges andhaving solid portions of said base between adjacent ends of said .slots, said aligned slots being transversely overlapped by the longitudinal edges of said blade and blade keep which bear on said solid portions, said base having a handle having a hole in theend thereof with a screw thread therein to take said screw on the razor blade keep.
